Patented ma a, rare.

Application filed August 12, 1915. Serial No. 45,205.

To all whom it may concern:

Be it known that I, FREDERICK C. OVER- BURY, a citizen of the UnitedStates, and a resident of Hillsdale, in the county of Bergen and Stateof New Jersey, have invented certain new and useful Improvements 1nMachines for Making Shingle-Strips, of which the following is aspecification. I

This invention has for its object to provide a machine which may be usedin the manufacture of shingle strips which may be used for coveringroofs, side walls and the like.

. As set forth -in Letters Patent No. 1,150,298, granted to me on the17th day of August, 1915, shingle strips are formed of what is known asprepared roofing mate'- rial; that is to say, a sheet or foundation offelt or equivalent fibrous material saturated or impregnated with arelatively low-melt- "ing-point pitch, asphalt or other hydrocarbon andcoated on one or both faces with pitch or asphalt, themelting point ofwh ch is high enough to prevent injurious actlon thereon by solar heat.This pitch or asphaltv shingle strips, and for forming on that portionof the strip, which is to be exposed when laid in overlappingrelation toothers, tabs or projections of predetermined shape or configuration,which, when the shingle strips are laid, simulate tiles or shingles.

Qn the accompanying drawings,Figure 1 represents in plan view a machineembodying the invention. Fig. 2 represents a longitudinal sectionthrough the same on the line 2-2 of Fig. 1. Fig. 3 represents one of thecutters. Fig. 4 illustrates a shingle The invention contemplatesthecombina I tion ofmechanism for feeding the elongated sheetlongitudinally, cutters for forming longitudinal slots arranged in rowsacross the sheet, and means for severing the sheet in a lineintersecting the slots of eachtrans- -verse row. It will be quiteevident that these several elements or instrumentalities may takedifferent forms and be arranged in different ways without departing fromthe spirit and scope of the invention.

In the embodiment of the machine as shown, the cutters for. forming therows of slots are so arranged and formed as to cut into the sheet pairsof longitudinal slits of the same length connected at their rear ends bycross slits so as to leave tongues attached at one end of the body ofthe sheet. Preferably the draw rolls or feeding rolls are from theshingle strip which is completedby the severing cut. The severed shinglestrips, as they are cut successively from the sheet, are received byopen carriers which feed them away from the machine and permit thedetached tongues to pass therethi-ough and not become commingled withthe finished product. Preferably the feeding of the sheet is continuous,the parts being so timed that the sheet is fed a. predetermined distancebefore it is severed transversely into sections by the chopping knife.

Referring to the drawings, the machine there shown is provided with aframe-Work of any suitable character, and may comprise ings are wellknown, I have not shown them in detail. Power is transmitted to thesefeed rolls by a train of gears which I shall subsequently explain.

The sheet of roofing A is drawn either from a roll or it may be drawndirectly from the machines in which it is saturated, coated and surfacedwith crushed mineral. As it enters the machine embodying the presentinvention, it passes between coacting'cutters which are indicated as awhole at 14: and 15. The cutters 1a are adjustably secured upon a shaft16, whereas the cutters 15 are adjustably secured upon. a shaft 17, bothshafts being journaled in suitable bean ings in the framework. Eachcutter 15 consists of a disk of the desired width, having on itsperiphery thetwo shear blocks 18 and 19. The side edges of the block 18are in shearing relation with the slittingblades forming a part of thecutter 1 1, whereas the end edge 18 of the block 18, and the block 19cooperate with a cross blade forming a.

part of the same cutter 1 1. These shear blocks 18 and 19 are securedupon the cut ter 15 by any suitable fastenings. Each cutter 15 comprisesa hub 20 formed at the end with a peripheral flange 21. To each face ofthe flange are secured two segmental slitting blades 22 which areadapted to coiiperate with the shear blocks 18 of the coacting cutter15. The flange 21 is provided with sockets 23 to receive thecross-cutting blades 24;, the chisel edges of which cooperate with theend edges 18* of the shear blocks 18. The blades 24 are secured in theirsockets by screws or other fastenings 25, the flange 21 being recessedto receive the same as shown in Fig. 6. Each cutter, as thus described,is

provided with two sets of knives or two sets of shear blocks as the casemay be, so that, during one complete revolution of the coacting cutters,two sets of slits will be formed in the sheet. The blades 22 and theircooperating shear block 18 will cause the formation of parallel slits bb as shown in Fig. 7, the rear ends of these slits to be connected by across slit 0 formed by the blade 24- and its cooperating shear block 18.This causes the formation of tongues al which are forced upwardly by theshear blocks from the plane of the sheet and which are attached at theirfront ends 0 to the body of the sheets As the sheet passes hatween therollers, the tongues cl are received by the grooves 13 of the feed roll12 and are not forced back into the plane of the sheet so as to stick oradhere to the walls of the slot. The material, which is employed forimpregnating the sheet, is more or less sticky and adhesive, and, whenthe tongues are forced back into the sheet, they stick in the slots andare difiicult to remove; whereas, by forcingthem out of the slots, theydo not adhere when the sheet is subsequently transversely severed. Afterleaving the feed rolls, the sheet A passes over a shear block or bed 26with which cooperates a chopping blade 27 secured on a rotatable cutter28. The latter is relatively heavy and solid so as to insure a severingout which will be clean and not ra ged. This cutter 28 is secured uponashaft 29 journaled in hearings in the frame-work. The parts are sotimed that the cutter 28 severe the sheet on a line f (see Fig. 7) whichintersects the ends of the slits b so as to cause the severance of thetongues cl at their attached ends. As a result, each severed portion ofthe sheet constitutes a shingle strip, such as shown in Fig. 4: at g andhaving a plurality of tabs or projections h separated by recesses '5.These tabs or projections can be formed of difierent widths, accordingto the adjustment of the cutters 1d and 15 on their respectiveshafts l6and 17, and I employ interchangeable feed rolls 12 having groovescorresponding to the width of the recesses so as to receive the tonguesas previously explained.

Below the shear block there is an inclined plate 30 On which the severedportions of the sheet or the shingle strips slide until they arereceived by the open endless carriers 31. These carriers consist ofchains or other suitable endless belts mounted upon sprockets 32, 33, orequivalent devices. The sprockets 32 are'upon a shaft 34 journaled inthe frame-work, whereas the sprockets 33 are on a shaft 35 journaled inbearings upon the ends of brackets 36 secured to the framework. As thefinished shingle strips are being carried away in the direction of thearrow in Fig. 2, the severed tongues drop between the several carriersand accumulate in a pile without becoming mixed or intermingled with thefinished shingle strips.

It is quite evidentthat the draw or feed rolls, the slitting cutters andthe chopping mechanism may be all operated in proper 12o timed relationby any suitable power-transmitting mechanism. As illustratingconventionally a suitable means for accomplishing this purpose, I haveshown the machine as being provided with a driving pulley 37 on theshaft 3A. This last-mentioned shaft has a gear 38 intermeshing with anddriving a large gear 39 on the shaft 29. On the other end of the shaftthere is a pinion 40 engaging a gear 41 journaled on the stud 60comprising means for longitudinallyfeedmeans shaft and intermeshing withan idler gear 12 likewise mounted on the stud shaft and all on the frontside of the machine. last-mentioned idler gear 42 intermeshes with anddrives a gear 43 secured on theend of the lower feed roll 11. On therear end of .the last-mentioned roll and on the like end of the roll 12are 'intermeshing gears 44, 45, to cause the two feed rolls to be drivenin unison. From the-gear 44; power is transmitted to a gear 46 on theknife shaft 17 by an intermediate idler ear 47. The gear 46 intermesheswith the gear 48 formed on the knife shaft 16. In lieu of the train ofgearing which I have just described, any other suitablepower-transmitting mechanism may be utilized.

A sheet of roofing having been prepared as herein described, on beingfed through the machine, has formed therein the longitudinal pairs ofslits, the slits of each pair being connected by the cross slits andthus forming attached tongues. Thereafter the The sheet is severed toprovide a series of shingle strips.

The invention, as herein described, and embodied in a suitable machine,is capable of producing shingle strips in large quantities and at verysmall cost. The sheet, during its travel-through the machine, may beguided by any suitable guides, but I have not shown them as theyconstitute an obvious mechanical expedient.

It is evident that the longitudinal slits 'of-each pair of slits neednot necessarily be straight or parallel, and that cutters of other formsmay besubstituted therefor to produce tabs or projections of differentshapes and in simulation of ornamental tiles or shingles. So far as anycommon generic inventions or improvements as herein claimed areconcerned, this is a continuation in part of my previous applicationSerial No. 23,153, filed April 22, 1915.

Having thus explained the nature of my said invention and described away of making and using the same, althoughwithout attempting to setforth all of the forms in which it may be made or all of the modes ofits 'use, what I claim is: 1. A machine for making shingle strips,comprising coacting feed rolls for longitudinally feeding an elongatedsheet of roofing felt, cutters on one side of saidfeed rolls for formingtransverse rows of longitudinal tongues in said sheet, and a chop pingcutter on the other side of the feed rolls for transversely severingsaid sheet on a line intersecting the 'bases of saidtongues. 2.
